写得挺好的,语法没问题啊.如果硬要说建议只有主语不要太长,句子容易头重脚轻.术语我不是特别会,但是修改简洁的话或许可以尝试这么写：
With transistor size shrinking,microsystem design is continuously challenged by variation of process,requirements for low supply voltage and power consumption,as well as complexity of modelling.Higher working frequency of computing units adds to the problems such as memory wall,high power consumption,etc.These difiiculties call for new architecture and electronic devices to be conceived/developed.
